Abstract

The grinding process is affected by many factors. These include the selection of grinding wheel, the dressing condition and of course the grinding condition. In addition, the performance of the grinding wheel changes considerably during the grinding process. Therefore, it becomes important to monitor the dressing as well as the grinding process, so that the required result is achieved. In this study the acoustic emission (AE) signal is used to monitor these processes. The dressing process is monitored to produce a grinding wheel surface of constant quality. The tool life of the grinding wheel can be defined by monitoring the change of the amplitude and the frequency characteristic of the AE signal. Contact between the grinding wheel and the workpiece can be successfully detected with the AE signal, which means that this method is effective as a gapeliminator.
